DEVICE FOR HOLDING CARBON-PAPER FOR COPYl'NG PURPOSES.

SPECIFICATION forming part Of Letters Patent NO. 428,856, dated May 27, 1890.

Application filed June 3, 1889. Serial No. 313,002. (No model.)

To aZZ whom it may concern.-

Be itknown that I, WILLIAM H. PARDEE, of Antigo, in the county of Langlade and State of WVisconsin, have invented a new and useful Improvement in Devices for Holding Carbon-Paper for Copying Purposes, of which the following is a full, clear, and exact description.

This invention consists in a combined surface-plate and carbon-paper holder constructed substantially as hereinafter described, and poi nted out in the claims, and which is adapted to be used by slippingit in between the leaves of a copying-book, writing-pad, or tablet, to give a smooth writing surface or support, and which also serves as a carrier of the carbonpaper and holder of it in proper position when in use.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding, parts in all the figures.

Figure 1 represents a view in perspective of a surface-plate and carbon-paper holder, as seen from its one side, embodying my invention. Fig. 2 is a similar view of the same applied as for use between the leaves of a writing-pad, and Fig. 3 is a transverse section of the device in a dismembered condition.

A indicates the surface-plate of the device. This plate maybe made of metal, card-board, or any other suitable material that will give a smooth and firm surface for the paper being written upon or above it. Upon the one side or back of this surface-plate A is a pocket I), that will serve to hold any extra number of carbon leaves or sheets. This pocket is permanently closed on its one end or edge, which forms the bottom of the pocket, also the side margins of the pocket being similarly closed; but the other or lapel end of the pocket is closed by doubling it over the edge of the surfaceplate and securing it there by a removable hollow clampingstrip or binder B. Upon the outside, too, or one face side of the surfaceplate A, whether made with or without a pocket, as above, are placed one, two, or more of the carbon-leaves c, which are held in position thereon by lapping their one edge or end over the edge of the surface-plate, to which the hollow clampingstrip or binder B is applied, and then slipping over the same and .over the marginal portion of the surfaceplate the hollow or grooved binding-strip B. This binding or clamping strip is made of spring metal bent over upon itself and of enlarged dimensions at its head or bent side to give it a more eiiicient elastic clamping action to hold the carbon-sheets c tight to the surface-plate. On a corner of each sheet of carbon-paper opposite to the side on which said sheet or leaf is clamped to the surfaceplate is gummed or otherwise secured a projecting tag cl, of plain paper or other suitable material, to facilitate the taking hold of and turning of the carbon-leaves without soiling the fingers.

The whole device can be used in any copying-book, writing-pad, 0r tablet-as, for instance, in a writing-pad D-by lifting any number of the sheets of the pad and slipping the surface plate or board A beneath the same and interfolding or interposing the carbonleaves 0 on the outside of the surface-plate between the leaves e of the pad or book, as shown in Fig. 2.

The device, too, holds the carbon-leaves in place while writing upon the top or exposed leaf of the pad or book, and it is quickly removed or replaced and does not get out of shape in handling.

The back pocket I) will be found very convenient for storing carbon sheets or leaves to be used, as required, on the outside of the surface plate or board by removing the clamping-strip B and afterward replacing the same. Such pocket will, for instance, be very useful to traveling salesmen, who will then have the carbon-paper where they can get at it quickly and readily adjust it to the edge of the surface plate or board. Said pocket I) may be made of paper or any light fabric that will answer the purpose. In come cases, however,

copying purposes, a Writing surface plate or board adapted to slipin between the leaves of a copying-book, pad, or otherlike article, i 11 com bination \vith'a clamping plate or strip applied to the edge of said surface-plate and adapted to admit of the entry and removal of the carbon paper or sheets.

2. In devices for holding carbon-paper for copying purposes, the combination of a writing surface plate or board adapted to slip in between the leaves of a copying-book, pad, or other like device and provided with a pocketfor storing sheets of carbon-paper, and a clamping plate or strip applied to the edge of said surface-plate and adapted to admit of the entry and removal of the carbon paper or sheets.

3. In devices for holding carbon-paper for copying purposes, the combination, with the plate or board A, of the removable hollow or grooved spring clamping strip or binder 13, and one or more sheets 0 of carbon-paper secured on the face of said surface-plate by said clamp, essentially as described.

4. In devices for holding carbon-paper in independent sheets, the combination, with the plate or board A, of the spring clamping strip or binder B, the sheets 0 of carbon-paper, and the tags (I, applied to the corners of said sheets on the edge or margin opposite to that by which they are secured to the plate or board by the clamping strip or binder 1- substantially as specified.

5. In devices for holding carbon-paper for copying purposes, the combination of the writing surface plate or board A, provided with a storage-pocket l) for the carbon-paper, and the removable spring clamping strip or binder l3, essentially as shown and described.
